When it rains it pours.
Shortly after finding the beat-up Kellison J5, a Kellison/Astra X300GT appeared. After some discussion with my brother, we decided two Kellisons were better than just one. The X300GT is just a body, and it looks like it's still mounted on the shipping stand.
Build two at the same time? It could happen. First order of business is to bring it home, then, build a frame.
